JS/TS language features keep restarting

Nobody has claimed this yet.

Type: Bug

Unfortunately, I have no idea how to reproduce this, but am happy to demonstrate in a pairing session with someone.

Description: For the last week or so, I've seen VS Code attempting, and failing, to fully load its JS/TS language features. VS Code eventually shows a prompt, which reports that the extension has crashed and been restarted repeatedly in the last five minutes, and that it may be related to the Svelte plugin. However, I have disabled that plugin (as well as the Glint plugin we use for our Ember code) and it continues to occur, and in fact I have done the "Reload with extensions disabled" command and that has the same problem.

VS Code version: Code 1.74.3 (Universal) (97dec172d3256f8ca4bfb2143f3f76b503ca0534, 2023-01-09T17:07:18.579Z)
OS version: Darwin arm64 21.6.0

Start by reproducing the repeated language-feature crashes in VS Code 1.74.3 on macOS, including with extensions disabled, and review the listed Svelte and Glint extensions as possible context. Done means identifying the component and conditions responsible, with a reliable reproduction or diagnostic result that can guide a fix.
